The paper draws some valuable conclusions : the limited bearing capacity of manual excavation filling pile is much higher than the limited bearing capacity of machine drilled filling pile ; through grouting injection around the pile shaft, the pile bearing capacity can be effectively improved ; proportion of resistance force around the pile side in total load is much larger than that of pressure on the pile tip, and the intensity of resistance force around the pile side is 30 - 50kpa on average
得出一些有價值的結論：人工挖孔灌注樁的極限承載力明顯高於鉆孔灌注樁的極限承載力；地下水位對樁基承載力有顯著影響；利用樁側注漿可有效提高樁的承載力；樁側摩阻力所佔總荷載的比例遠大於樁底壓力，樁側土的摩阻強度平均值為30 50kpa 。
